IF YOU ORDER THIS PART AND IT'S NOT TO GO ON A BIKE IN THE BASKET. THE ORDER WILL NOT BE SENT AND YOU'LL RECEIVE A REFUND WITHIN 48 HOURS MINUS AN ADMINISTRATION CHARGE.

Once installed it doubles the cut off speed. It can also be used with the Bosch S pedelec motors as it works in the same way. The dongle can be easily unplugged whenever necessary to revert the bike back to normal.

The display will read the wrong mph, when the dongle is operating the speed and anything related to speed is halved, so it should be doubled for a true reading. It's simple, if it says you are going 5mph then you are actually going 10mph. As soon as it's unplugged the speed readout will revert back to normal.

Please Note: We use the reference to Bosch in the sense that this will fit Bosch powered eBikes. This product is not manufactured, produced or endorsed by Bosch themselves.

This can be added at time of purchase but please note that if workshop time is requested to fit further down the line we will be happy to assist however a small labour charge will be added.

By going over the 15mph cut off these dongles are FOR OFF ROAD (PRIVATE LAND) USE ONLY! They may not be used on the road, cycle paths, bridleways or anywhere else where the public have access.

Tuning devices are supplied on the basis that they may only work with the software version of the bike supplied at the time of supply & no warranty or guarantee is given that these will continue to work with future software versions or upgrades.

Very good piece of kit. Transforms the bike. The dongle does need extra covering as it is prone to becoming loose and will cut out when wet. I tape the whole thing up in insulating tape. I expect there maybe issues in the winter and rides with deep wet mud etc.

So as you can see I shaved 4 minutes off my lap time. I also boosted my average speed from 12.5mph to 13.8mph This sort of performance over such a short distance has proved the dongle helps considerably!

Wow! Amazing! Great! Super! Yes!!!! (is the basic experience). Wow what a difference it makes - no longer are you just getting interested and the motor cuts out! Oh no! The thing just keeps going! F****** ace.

Just what I wanted. I don't know what else to say - I can only say that it is now exactly the bike I thought it could be. Only one other mod I did was to put a 45T chainring on it to deal with the higher top speed.
Otherwise I would say the bike is pretty much perfect.
